Nope.
I would say mounts should be more expensive, because you could transfer them to other expansions and realms.
These prices should be added way before merging.
Still, boosting, renaming, customization.... Is per one server, one realm, one character and yet 3 times more expensive.
I won't even go further in this, or else I'll get pissed.
+ Buying points over the phone is just ROFL...........
